Skat is a popular German card game played with a deck of 32 cards that consists of the cards 7, 8, 9, 10, jack, queen, king and ace in all suits, without jokers.

Every one of the three or four players plays for himself, but in every single game one player, selected by the bidding process, plays against two others. When there are four players, each player skips one round out of four. The two opponents are not allowed to communicate in any way except by their choice of which cards to play.

The main goal in normal games is to score more than half of the card points, i.e. 61 or more out of 120. A declarer who manages to do this is awarded game points, a declarer who fails at this loses game points. At the end of the evening or of the particular round, the player with the most game points wins the round. [Wikipedia]
